Samsung announced a global recall of the phone in mid-September after incidents in which the batteries overheated or caught fire. It said its replacements were safe, but several people have said those phones caught fire. Last week, a Southwest Airlines flight was evacuated because of a phone that was smoking and making "popping" noises after it was turned off.

On Saturday, a Kentucky man wrote in a Facebook post that his replacement phone caught fire Tuesday night, and he posted photos that he said showed the damaged phone. The man, Michael Klering, said he and his wife inhaled smoke from the burning phone and now have bronchitis.

On Sunday, two U.S. mobile carriers said they will stop issuing Samsung Electronics' new Galaxy Note 7 smartphones due to safety concerns, CNBC reported.

AT&T said it would stop giving consumers replacement Galaxy Note 7 smartphones because of reports that some of the replacement phones are catching fire, just as the original phones did before they were recalled last month. AT&T encouraged customers with Note 7 phones to exchange them for other products. AT&T hasn't sold Note 7 phones since the initial recall was announced. Verizon, another major seller of smartphones, said it doesn't have any Note 7 phones but said they are on back order.
